Maleypay was a male Nadurni.
He was the science tribune of the Nadurni war effort. In 1827 he was the leader of three Nadurni, who came to the Amazon rainforest.
There they experimented with animals and used a gene manipulator on them. They wanted to turn these animals into strong fighters, so that they could win a war for them. Later they also wanted to turn the Eleventh Doctor into a monster that would fight for them. However, the Doctor was saved by Oliver Blazington. Maleypay, Ventor, Cairow and Oliver Blazington died in the explosion of their space ship. (AUDIO: The Eye of the Jungle)
